Bakteri Vibrio harveyi merupakan penyakit bakterial yang banyak dijumpai pada kegiatan budidaya perikanan. Penggunaan antibiotik dalam pencegahan dan pengobatan serangan penyakit menyebabkan efek negatif. Daun Ketapang (Terminalia catappa L) diketahui mengandung senyawa kimia seperti flavonoid, alkaloid, fenolik, tanin, dan saponin yang dapat berperan sebagai antibakteri. Penelitian ini bertujuan untuk mengetahui daya antibakteri ekstrak daun Ketapang terhadap pertumbuhan bakteri Vibrio harveyi. Uji daya antibakteri dilakukan dengan 5 jenis perlakuan yaitu 1 perlakuan tanpa daun Ketapang (kontrol) dan 4 perlakuan daun Ketapang dengan konsentrasi yang berbeda yaitu 15, 30, 60, dan 120gram daun ketapang/liter. Masing - masing perlakuan terdiri dari 3 pengulangan. Ekstrak daun Ketapang menunjukkan daya antibakteri terhadap pertumbuhan bakteri Vibrio harveyi dengan rerata hambatan masing – masing konsentrasi (Mean ± SEM) yaitu 7,53 ± 0,13 mm (15 gram/liter); 7,70 ± 0,36 (30 gram/liter); 8,25 ± 0,15 (60 gram/liter); and 9,62 ± 0,83(120 gram/liter). Perlakuan tanpa daun Ketapang (kontrol) tidak menunjukkan daya antibakteri. Ekstrak daun Ketapang menunjukkan daya antibakteri terhadap pertumbuhan bakteri Vibrio harveyii dengan daya antibakteri sebanding terhadap konsentrasi ekstrak.

Vannamei shrimp cultivation in Indonesia has begun in East Java. Farmers in East Java cultivate vannamei shrimp, in fact 90% of farmers have replaced the tiger prawns they cultivate with vannamei shrimp. With the increase in vannamei shrimp cultivation, it is necessary to provide continuous and quality fry, so it is hoped that it will be able to increase the productivity of vannamei shrimp. The purpose of this writing is to determine techniques for rearing vannamei shrimp larvae (Litopenaeus Vannamei) at PT. Delta Windu Purnama Situbondo, East Java. The methods used in rearing vannamei shrimp larvae start from preparing rearing tanks, preparing equipment, installing aeration, fumigation of rearing rooms, preparing rearing water, stocking naupli, managing feed, managing water quality and harvesting and packaging the fry. The results obtained were that the number of larval populations produced at the end of the rearing period in tank B1 was 2,000,000 with a survival rate of 80% and in tank B5 was 2,370,000 with a survival rate of 94.8%. The population number and survival rate of vannamei shrimp larvae will decrease along with the change of larval stage which is influenced by environmental conditions and food availability. The water quality parameters for rearing vannamei shrimp larvae that were measured were temperature 28-31.5°C, salinity 30-31 ppt, pH 7.7-8.1 and dissolved oxygen 5-5.7 mg/l.

In addition to having high economic value, catfish (Clarias sp.) can also be cultivated quickly and they can adapt well. The demand of catfish is in line with the increase in production which is expected to remain efficient and environmentally sound. Biofloc technology has also been implemented in catfish for increasing productivity. Biofloc utilizes the activity of heterotrophic microorganisms and autotrophs for the conversion of organic waste into floc and is used as fish feed. This study aims to examine the effect of the use of molasses with different doses (C/N ratio) on the growth and survival rate of catfish. This study was conducted with as many as 3 treatments with 3 repetitions each except for the control. The treatment with the ratio of molasses in each of them: A: C/N of 10:1; B: C/N of 15:1; C: C/N of 20:1, and D without molasses given as control. The study using 240 catfish measuring 10-12 cm was carried out for 30 days with sampling every 10 days. It aims to determine the average growth, daily growth, and survival rate of test biota during the study. Based on the results of this study, it can be concluded that the use of different doses of molasses in catfish farming, and biofloc technology will affect the growth and survival rate of farmed catfish. Catfish farmed with biofloc technology at a C/N ratio of 15:1 show the best results on their growth and survival rate. In addition, catfish farming with a biofloc C/N ratio of 15:1 has a better economic analysis when compared to conventional catfish farming. In summary, the use of biofloc based on research results can be a recommendation to be applied in the community, especially among catfish farmers.
